Some people suggest allowing the galvanised metal to weather outdoors for a
few months.

says..
"You must first apply an etching (or bonding primer). This can be either a
Zinc Phosphate primer or a Calcium Plumbate (not suitable for spray because
of lead content) primer. If it is difficult to find these an Acrylic or
Latex Metal primer should be sufficient for most jobs. "
